Power & time on Homey Bridge

Flows
1

Hi all,

I’m a bridge user and struggle finding a way to summarize power usage over a given time period. Here are two examples:

  1. Smart plug connected to freezer: I want to be notified if the freezer is broken. The compressor is on/off all the time, so I need something like “No power drawn in 3 hours”.

  2. EV charger load balancing: I want to stay below 10 kW total house consumption for each hour in order to avoid high power tariffs. I have instant power data from Tibber pulse AMS reader and need something like “If average power exceeds 10Kw for 5 minutes”, to trigger reduced charging speed.

It seems people with Pro’s use the “chronograph” function for these things. Is there a way to solve it on Bridge?

No. These are “advanced” use cases, Homey cloud is targeted at straight forward setups / non-tech users (as I understood from the marketing and Athom forum posts).

I also would never use these quite important checks with a cloud-only device, but that’s a personal opinion.

Thanks for the input. As feared I’m afraid.

This might work:

Create number-variable ‘compressor freezer not running’

WHEN:
Every 1 minute
AND:
powerconsumption is 0
THEN:
calculate ‘compressor freezer not running’ is {{‘compressor freezer not running’ + 1}}

WHEN:
Power consumption freezer changed
AND:
Power consumption is more then 50 watt
THEN:
Set ‘compressor freezer not running’ to 0

WHEN:
‘compressor freezer not running’ has changed
AND
‘compressor freezer not running’ is more than 180
THEN
Send notifications: “check freezer”

An “every 1 minute” card isn’t available @ Homey cloud.
But what’s possible is, using two similar flows, which start one another after 1 minute.
